the lower amps in the engine compartment
is because the engine aka chassis batteries are at a higher state of charge than the house batteries
the engine batteries don't get as much power drain during the camping as the house batteries
the isolator applies the same voltage to both outputs house and chassis
power absorbed by any battery at the voltage applied depends on the battery chemistry
the house batteries take more ..because they are lower SOC and need more

This morning's testing results
sat over night on house batteries only for power.
....................morning...................engine running.............Shoreline power
Engine.........12.61v .5amps..........14.3v 2.2amps............13.3v 0.0amps
Bat Monitor..12.7 v .6amps...........14.3v 12.1amps..........13.6v 4.4amps
House batt...12.43v .6amps..........14.02v 12.8amp...........13.29v 4.5amps
converter.....12.41v .5amps..........14.05v 0.4amps...........13.49v 4.8amps
nothing stands out to me. The lower amps in engine battery while engine is running is probably because the alternator is putting the amps to the house batteries.
Note that the engine is producing to the house batteries 14.02v and 12.8amps, while on shoreline power, the converter is producing 13.29v and 4.5 amps to them. Alternator is out performing the converter big time.
